Blender Crashing When Rendering Simple Scenes
This is a corrupt file on preferences. I´m sorry but you´re going to start blender anew afresh, asap. :)
go to: C:\Users\3DCompositor\AppData\Local\Blender\Cache
Delete everything you got in there.

Go to: C:\Users\3DCompositor\AppData\Roaming\Blender Foundation\Blender\2.79 or 2.8 whatever of the two folders you have there: delete it.

I´d assume you don´t have many new configurations or shortcuts. But even if you did, clearing out these locations will grant you a fresh copy of Blender.

Also go to: C:\tmp
And wipe out all traces of any myfile.blend you could have there. 

START BLENDER and if you CAN´T and Blender still crashes, the second thing to check is a FAULTY ADDON. Do you remember having added an ADDON recently? IF so: Please uncheck it and delete it from Blender´s addon folders:
C:\Users\3DCompositor\AppData\Roaming\Blender Foundation\Blender\2.79\scripts\addons

Last but not least try to run blender after all of these operations with only 1 monitor (YES ONLY ONE AFTER CLEANING) for a regular 10 minute session. IF you don´t notice anything weird, proceed with the SECOND monitor (plug your monitors with your PC OFF!)
Work for 10 more minutes using BLENDER. If you didn´t have any crashes, Turn off PC, connect 3rd monitor, and work with Blender for 10 more minutes.

If Blender crashes while you render while you have monitor A, B, or C connected you´ll know which one could possible be malfunctioning.

All right, thank you if you vote me as the answer.
